Title: Photonic trumpets: an attractive resource for quantum photonics
Session: 10:10


Over the last twenty years, many groups have used optical microcavities to tailor the optical properties of solid-state emitters, including their spontaneous emission, and to develop a novel class of photonic devices such as microlasers, single photon sources and quantum optical gates. Exploiting high Q cavities induces various drawbacks, for instance the need for a spectral matching of the cavity mode and the emitter, and the sensitivity of their radiation pattern to structural imperfections. In this lecture, I will introduce the photonic trumpet, a tapered photonic nanowire which acts as an ideal broadband dielectric antenna coupling the emission from an artificial atom to a low NA Gaussian mode. I will review various applications of photonic trumpets in the field of quantum photonics (e.g. high efficiency and widely tunable single photon sources), non-linear optics and quantum sensing.


Jean-Michel, GERARD received his PhD degree in Physics from Paris VI University in 1990. He has been in charge of QD research at France Télécom R&D in Bagneux from 1995 to 2001, head of the Nanophysics and Semiconductors CEA-CNRS team in Grenoble from 2001 to 2005, and Head of the Physics of Materials and Microstructures laboratory (CEA/SP2M) since 2005. From 1997 to 2009, he has also been Physics Professor at Ecole Polytechnique, Palaiseau. He has given pioneering contributions to the development of QD growth method and to nanophotonics (single QD spectroscopy, cavity quantum electrodynamics experiments with QDs, QD single photon sources) for which he has received the "Prix fondé par l'Etat" from French Academy of Sciences in 2005 and the "Quantum Device Award" founded by Fujitsu Corp in 2008. His present research aims at developing advanced optoelectronic devices based on QED effects in cavities or photonic wires, such as quantum light sources, microlasers and photonic switches. He has published around 350 papers indexed on the Web of Science (>10000 citations, H=50), presented more than 150 invited talks at international conferences and schools, and has registered 13 patents.
